FERRULE.

ssaiea.

To all whom it may concern:

Be it known that I, EDWARD GLENNAN, a citizen of the United States,residing at New York city, Brooklyn, county of Kings, and State of NewYork, have invented new and useful Improvements in Ferrules, of whichthe following is a specification.

This invention relates to a ferrule of novel construction for couplingpipes, and more particularly for connecting lead pipes to iron pipes.Such connections are frequently required in plumbing, for examplebetween the leaden drain or ventilating pipes of a closet and the irontrap. F or making the necessary solder joint between the lead pipe andthe ferrule, it is necessary that the solder receiving surface of thelatter be composed of brass or similar solderable metal. As aconsequence the ferrules have heretofore generally been constructedentirely of brass, but as this metal is expensive, quality hasfrequently been sacrificed by unduly re ducing size and weight.

By my invention, a strong and serviceable ferrule is obtained at greatlyreduced cost, so that with but small expense an entirely reliable jointcan be made.

The accompanying drawing represents a longitudinal section of myimproved ferrule showing it in use.

The ferrule is composed of two parts, viz: an iron sleeve 1, and a brassor similar solderable bushing 2, which is overlapped by the sleeve andis firmly united therewith. Sleeve 1 has a flaring end 3, and bushing 2is correspondingly flared as at 1 to be flush with the sleeve. Withinflaring end 3 there is formed on sleeve 1, an integral flange 5, and inassembling the parts, the cylindrical end 6 of bushing 2 is insertedinto the sleeve so as to be telescoped thereby. This cylindrical section6 is set back from the face of bushing 2, and its outer diametercorresponds substantially to the inner diameter Specification of LettersPatent.

of flange 5, so that While the face of the bushing 2 is flush with theface of sleeve 1, the cylindrical section 6 of the former is snuglyembraced by the flange 5 of the latter. After section 6 has beenintroduced into the sleeve in the manner described, that part thereofwhich underlies flange 5 is expanded against the inner wall of thesleeve as at 7 so that the parts become intimately united. It will beseen that the compound ferrule thus obtained is composed of twotelescoping and firmly united end sections, the relative proportion ofthe parts being such that the cheaper iron section 1, is considerablylonger than the more expensive brass section 2. At its lower end, sleeve1 is provided with an integral outer flange 8, and is here adapted to becalked into a trap or similar iron device 9, as at 10.

The lead pipe 11. which is to be connected to bushing 2 may be setagainst the end of the latter, and soldered thereto by a wiped joint 12.If desired however, the pipe may be inserted into the bushing to restagainst an inner shoulder 18 thereof, and then the wiped joint may beformed at the junction of the parts.

It will be seen that my ferrule is of great strength, is thoroughlyserviceable and may be manufactured at a low cost.

I claim:

A ferrule composed of an iron sleeve having an inner flange at one endthereof, and of a solderable bushing which is flush with the sleeve andhas a set back cylindrical section which is embraced by the flange, andprojects with its end beyond the same, said projecting end beingexpanded against the inner face of the sleeve.
